I wouldn't put an Oscar in a 55. You are inviting sickness upon your fish. You COULD do gigantic bi-weekly water changes, but why make your life difficult when you don't have to? Not to mention that if you miss a week, your fish suffers.

A school of exodons would be cool.A sole Delhezi will live in a 55 for life. It may be a bit cramped. Or a few senegal bichirs. A single oscar , exodons , Needlefish! All of these with the exception of if you only got like 3-4 exodons require a 55 gallon.chris1993;3288899; said:im in a similar situation lol i wa maybe thinking bichir or something ..there are probarbly hundreds of fish that eat other fish and are predatory sutable for a 55 but none ever get suggested or you will find out to late lol![]()
